Dear ?!r. Harris,
Thanks very much for the interesting series
of publications forwarded to me, I am delighted
to see how many important things have been published.
I am writing the article promised and shall
send it within a few days. I wonder whether as a
payment I could get Prof.Haberlers' book "Readings
on Business Cycle Theory.

Thanking you in advance,
Very sincerely yours
